Question

The baby is four and a half months old. When I support him to learn to walk, his right leg walks well, but his left leg is reluctant to move forward and often steps on the right leg. Why is that?

Answer

Based on your description, the baby’s brain’s nervous system is not fully developed at four and a half months old, which may be the reason why he is reluctant to move his left leg forward and often steps on his right leg when learning to walk. As the baby grows older, this condition will gradually improve. By the time the child learns to walk, this problem should disappear.
